HENRY F. COX, OF ALTOONA, PENNSYLVANIA.

RAILWAY-CROSSING.

SPECIFICATION forming part of Letters Patent No. 262,931, dated August22, 1882.

Application filed February 28, 1882. (No model.)

. To all whom it may concern:

Be it known that I, HENRY F. COX, of Altoona, county of Blair, and Stateof Pennsylvania, have invented new and useful Improvements inRailway-Crossings; and I do hereby declare that the following is a fulland exact description of the same, reference being had to theaccompanying drawings, and to theletters of reference marked thereon.

This invention consists in a special arrangement of turn-out switches ata railroad-crossing, by means of which it is made absolutely impossiblefor one train to collide with another, as will be fully describedhereinafter.

In the drawings, Figure 1 represents a railroad-crossing with my specialarrangement of turn-out switches, the line B in this view being open forthe passage of a train to its destination and the line 0 closed againstthe passage of a train, but open onto both of its turnout switches; Fig.2, a similar view with the line 0 open for, the passage of a train toits destination and the line B closed against the passage of a train,but open onto both of its turn-out switches; Fig. 3, a double crossinghaving the same arrangement of turn out switches.

To enable others to use my invention, I will proceed to describe fullythe arrangement of the same.

A represents an ordinary railroad-crossing, with the main tracks B and 0connecting therewith in the usual manner. D represents a turn-out bymeans of which a train coming on the track (J in the direction of thefull arrow is switched olf when the track B is open for the passage of atrain, as shown in Fig. 1. E represents a turn-out by means of which atrain coming on the track 0 in the direction of the dotted arrow isswitched off when the track B is open for the passage of a train, asshown in Fig. 1. F represents a turn-out by means of which a traincoming on the track Bin the direction of the full arrow is switched offwhen the track 0 is open for the passage of a train, as shown in Fig. 2.G represents a turn-out by means of which a train coming on the track Bin the direction of the dotted arrow is switched oli' when the track 0is open for the passage of a train, as shown in Fig. 2. The switches ofthese turn-outs, it will be observed, are so connected by pipes wandcranks 00 that a single switch-lever, 00 may be employed, if desired, ora system of interlocking levers, if desired, the construction being suchthat when one main line is open for the passage of a train the other isclosed to the passage of a train, but is in connection with its turn-outswitch, so that even if two trains approach each other at the crossingone will pass on to its destination, while the otherwill wait or heswitched off onto its turn-out. A collision between two trains at thecrossing is thus made impossible.

This invention is applicable also to a double crossing, as shown in Fig.3.

I am aware that a turn-out switch has been employed in connection withdraw-bridges, and therefore I do not broadly claim such a construction;but,

Having thus fullydescribed my invention, what I claim as new, and desireto secure by Letters Patent, isp In combination with a railroad-crossinghaving the main tracks B and O and the turn-out switches D, E, F, and G,actuating mechan- 75 ism, substantially as described, by means of whichthe switches are moved in unison to protect the track which is open forthe passage of trains.

This specification signed and witnessed this 80 27th day of February,1882.
